TRUCK.

Application filed November SM. 19%. Serial. No. 150,549.

The present invention relates to an improvenient in stair climbingtrucks.

The object ot the invention is to produce a truck for carrying goods upstairs. llt linds a considerable use in tahingr ash. barrels from thecellar. To this end the present invention consists in the stairclimbing); trucl hereinafter describedv and particular y defined in theclaims.

In the accompanying (ll'tlWlllgl-l illusl'rat ing the preferred torrn otthe invention, Figs. 1, E2, and 3 are medial sections of a truck shownin ditlerent positions on s airs, thus, Fig. l. ro ling); along; thetread: l ip 2 in position to engage a step. and Fig. 3 the position ofthe parts after the truclt has been raised. to the next tread: l: is afront elevation of the truck: and Fig. l) andv 6 show details 0tconstruction hereinafter referred to.

The truck has a frame 10. and may be made of channel iron with the openside inward. The trains is provided at 11 with journals for the shaft12, having the wheels 13 upon which the truck may roll. A trans" versemember 14 extends from side ineiu'iher to side member of. the frame, andatlords a support for the top of the barrel. The barrel 15 is shown indash and dot lines in Fig. 1. A cross shaft 16 is fastened between theside members of the frame. A bar 17 has an eye at its upper end whichQllllll:t@$ this cross shaft. The lower end ot the bar 1.7 is secured tothe center of the cross piece 14;. Upon the bar 17 mounted a barrel clip'lll, so that it may slide up and down on the bar. and its lower end mayengage the top 0? a barrel andv hold it on. the truclr. M

A. cross head 19 is provided. near the lower part of the truck, whichhas enlarged heads 20 (see Fig. 6) received in the open channel. of theframe 10. This cross head is adapted to slide up and down in the groovesin the t vo channels of the side members, the portions oil the sidemembers between which the cross head slides beinp; parallel. to eachother, as shown at the bottom o'l Fire; 4-. The cross head carries astair prone; ill secured to the middle ot the cross head. This prone;ill is provided with a slot 29; which receives the lower end 23 ot thelinl: 2 1-. This link is bent at um lower end. as shown in 5. and. thetlatportion oi. the link engages the end of the slot 25%, as shown in Fi5. thereby preventing the prong from turning to an angle extendingupward from the cross head.

The linli; constitutes means tor actusting; the prong; and for movingthe prong and cross head up and down on the ilfraine. The upper end ofthe link is pirotally connected to one end of a hand lever 25. providedat its opposite end with a handle Elli. This hand. lever 25 is pivotallymounted on the cross shaft 16. being; conveniently provided with a hub27 which turns on the cross shaft 16. Conveniently the cross shattconsists of a stitl rod. extending); from trains to f ame, hearing twopieces of iron pipe. one o't which extends troi'n the ripght hand crossmember, as Viewed in lli l to and flush with. the tar side of: the eyeof the rod 17. and. the other oil: which extends troin the left handcross frame. as viewed in l. to the hub 97. These pipes on the barsupport the hub with the hand lever in proper position on the bar.

The truclt is operated in climbing stairs as :liollows: Assruningr abarrel to be carried by the truclr. the barrel is tipped away from thetruclt Sllfgl'llilji and the toe of the truck is pushed. under thebarrel. Then the hooh l8 dropped over the top ot the barrel and. theoperator, by placing his toot against the wheel. shaft 12. may pullbacluvardly upon the upper end ot the frame and therein lift the barrel.oil? the floor and tip it into the position shown in Fig. l. The truckwill then be backed up againsttbe stairs with the handle in the positionit occupies in Fig. 1. While in this position the prone will be abovethe ordinary height of riser oi the stairs. The truck will be rolledalong until it occupies the position shown in 2. and then the user willtake hold of the handle 26 and turn it from the position indicated inFig. 2 to the position indicated in Fig. 3. The turning ot the handlever will. he done with one hand while the truclr is steadied. inposition by the other hand. .ils the hand lever is pulled upon theprone; takes upon the step above the level of the wheels of the truck,and the lever pulls upward. upon the cross shalt 16. finding}; itsresistance to sui-h upward pull. in the pressure at the prone; againstthe step. The cross head carrying; the prone stands tast. and. thetruclr slides upward on the cross head. lVhen the truck wheels reach andrest upon a step, the hand lerer will be thrown down to the position.shown in Fig. l, thereby raising the prong till withrespect to thewheels to the position shown in that figure. The truck will then berolled back to the next step, the lever again pulled upon, and the trucklifted to that step, and so on to the top of the steps, whereupon thelever will be thrown down and the truek may be used to roll the barrelto the place Where it is to be put.

It is to be observed that the cooperation of the bent end 23 o! the link24 with the prong prevents the prong from turning to a positionprojecting upwardly from the cross head. In other words, when the prongis lifted by depressing the hand lever, the cross head must maintain aconstant position with relation to the link. Vhen the hand lever isdepressed to its extreme position, the link 24 strikes the cross shaft16 or the hub 27 or the eye on the bar 17, and the upper end of the link24 being moved toward the frame causes the lower end of the link to beswung outwardly, thereby causing the prong to be projected rear- Wardly.Simple provision is therefore made for making sure that the prong projects rearwardly in position to engage a step.

Having thus described the invention, what is claimed is:

1. A truck having, in combination, a frame having side members and atoe, wheels supported on the frame, the lower portion of the sidemembers being channelled on their inner sides, a cross-head having itsends pivotally and slidingly received in the open sides of the channels,a stair pron mounted on the cross-head, a hand lever pivotally mount edon the upper portion of the frame. a mmnection between the prong and thehand lever for operating the prong by the lever to lift the frame on theprone as a pivot.

2. A truck having, in combination, a fra me having an upright portionand a toe. wheels supported on the frame, a slide mounted on the lowerportion of the upright portion of. the frame, a stair prong carried bythe slide, and means for reciprocating the slide on the frame and swin,in; the prong rearwardly to engage a stair tread.

3. A trnek as defined in claim 2 in whieh provision is made to preventthe prone: from swinging upwardly upon the slide beyond a predeterminedpoint.
